An intra prediction method is described. The method can include determining a prediction value for a sample of a current block from one or more reference samples outside the current block by using an intra predication mode. The method can also include deriving a weighted prediction value, when one or more predefined conditions are not satisfied, wherein the one or more predefined conditions relate to at least one of a width and/or a height of the current block and the intra prediction mode. Furthermore, the method can include coding the current block using the weighted prediction value, when the one or more predefined conditions are not satisfied.
